The volume is the space it takes up, which would be the same. The mass is measured as the weight, and the steel ball would be significantly heavier. Density is mass/volume, and if the steel has a larger mass, it will therefore have a higher density.
Answer
Diatomic molecules are all molecules which contain 2 atoms of the same kind. Famous ways of remembering these are:
I bring cookies for our new home ⇒ Iodine, Bromine Chlorine, Fluoride, Oxygen, Nitrogen, Hydrogen.
Have no fear of ice cold beer ⇒ Hydrogen, Nitrogen, Fluoride, Oxygen, Iodine, Chlorine, Bromine.
Answer: 0.04M
Explanation:
Tetraoxosulphate(VI) acid has a formula of H2SO4.
The concentration of the whole acid is 0.02M, and there are 2 hydrogens in the formula. That means we multiply 0.02M * 2, giving the answer of 0.04M.
Another visual explanation...
H2SO4 = H2(2+) + SO4(2-)
There are two hydrogens, the double amount of concentration of H2SO4, giving the answer of 0.04M.
Answer:
The isotopic mass of 41K is 40.9574 amu
Explanation:
Step 1: Data given
The isotopes are:
39K with an isotopic mass of 38.963707u and natural abundance of 93.2581%
40K with an isotopic mass of 39.963999u
41K wit natural abundance of 6.7302 %
Average atomic mass =39.098 amu
Step 2: Calculate natural abundance of 40 K
100 % - 93.2581 % - 6.7302 %
100 % = 0.0117 %
Step 3: Calculate isotopic mass of 41K
39.098 = 38.963707 * 0.932581 + 39.963999 * 0.000117 + X * 0.067302
39.098 = 36.33681 + 0.0046758 + X * 2.067302
X = 40.9574 amu
The isotopic mass of 41K is 40.9574 amu
Non-polar Solute and Polar Solvent (and vice versa)
However the molecules in the solute and solvent are only able to make dispersion forces with each other (as they aren't both polar). This only releases very little energy. Therefore overall, more energy is required than released and hence the process won't happen.
